Abstract
The described examples provide a system and methods for identifying a location of a mobile device within an indoor venue using cellular communication signals obtained while the mobile device is within the indoor venue. An array of antennas arranged within the indoor venue detects cellular communication signals transmitted by the mobile device. The detected cellular communication signals have detectable and measurable signal parameters that allow the location of the mobile device within the indoor venue and an identifier of the mobile device to be determined. The determined identifier of the mobile device may also be used to identify the mobile device subscriber. The mobile device indoor location information may be used to update an anonymized subscriber profile associated with the mobile device subscriber.
